Nutrition 101

Introduction

Why what you eat matters

Food isn’t just fuel—it’s one of the most powerful tools we have for shaping our health. With over half of U.S. adults living with more than one chronic health condition, and more than three-quarters struggling with at least one issue like fatigue, poor sleep, weight gain, or difficulty focusing, what we eat has a direct impact on how we feel and function every day1.

Every bite you take acts like a set of instructions for your body, sending signals that support healing, energy, and resilience, or potentially trigger inflammation, stress, and imbalance2. Nutrition isn’t about strict rules or deprivation—it’s about understanding your body’s needs and using food as a powerful tool for feeling and functioning better every day.

Food is medicine

Think of your kitchen as your medicine cabinet. The concept of “food is medicine” means that what we eat can work like a daily prescription for our health. Instead of thinking of meals as simply a source of calories, this approach recognizes that food delivers powerful compounds that can protect the body from disease and help repair damage3. Conversely, some processed foods high in sugar, unhealthy fats, and additives can send the opposite signals—fueling inflammation and stress inside the body, which over time may increase the risk for disease4. In fact, research shows that eating nutrient-rich foods may lower inflammation, balance blood sugar, and support healthy gut bacteria, all of which can play a role in preventing chronic conditions5. That’s the idea of “food as medicine,” rooted in science and reinforced by daily results.

Core Components of Nutrition

At its core, nutrition consists of two main groups of nutrients. Macronutrients are the ones your body needs in larger amounts. They supply energy and provide the raw materials that make up your cells and tissues6. Micronutrients—such as vitamins and minerals—are needed in much smaller amounts, but they play an outsized role in keeping the body running smoothly. These nutrients are involved in everything from energy production to hormone balance and immune defense7. Together, macronutrients and micronutrients form the foundation for energy production, cellular repair, and resilience across all body systems.

Macronutrients

Macronutrients—protein, fat, and carbohydrates—are the big players in the diet, the nutrients your body needs in larger amounts every single day 8.

Protein: The foundation for strength and repair

Protein is a macronutrient made up of amino acids — the building blocks of the body. Once digested, those amino acids are used to repair tissue, build muscle, and produce enzymes and hormones that regulate everything from metabolism to immune function 9. Muscle is often called the body’s metabolic “engine.” When muscle mass is low, the risk of diabetes, chronic inflammation, and accelerated aging may all increase10. Beyond muscle, every cell and tissue in the body depends on protein—from immune molecules that fight infection to neurotransmitters that regulate mood and focus.

The 2025-2030 guidelines for Americans recommend 1.2-1.6 grams per kilogram for the average adult11. Research shows that some people may benefit from even more—in the range of 1.0-2.0 grams per kilogram depending on age, activity level, and health status12. For example, someone weighing 150 pounds may need between 68 and 135 grams of protein daily to support muscle and metabolic health, though exact needs will vary by individual.

A variety of high-quality protein sources can help you meet your needs:

• Animal proteins—from sources like wild-caught fish and pasture-raised eggs and meat—contain all the essential amino acids in the right balance for building and repairing muscle. They’re considered “complete” proteins because of their amino acid profiles, making them especially effective for building strength and supporting recovery.
• Plant proteins—from whole foods like beans, lentils, nuts, seeds, and tofu or tempeh—are also excellent, but may not provide the full range of amino acids in one source. If you follow a vegan diet, especially as you get older, it’s important to combine a variety of plant proteins throughout the day to cover your needs. In some cases, adding a high-quality plant-based protein powder—or supplementing with branched-chain amino acids (BCAAs)—can provide extra support for maintaining muscle and strength13.

Fats: Essential for hormonal, brain, and cellular health

Fat is a macronutrient made up of fatty acids that provides concentrated energy and structural support for the cells. Beyond fuel, fats help form cell membranes, enable absorption of vitamins A, D, E, and K, and are essential for producing many of the body’s hormones14. The right kinds of fats support hormone balance and brain function15, cushion and protect the organs, and allow the body to absorb key vitamins A, D, E, and K16. Some of the best sources include omega-3 fats from wild-caught fish such as salmon and sardines, or from plant foods like walnuts, chia, and flax seeds. Monounsaturated fats from olive oil, avocados, olives, and macadamia nuts are also excellent choices17.

It’s also important to be mindful of certain refined fats. Excessive intake of refined omega-6-rich seed oils (such as soy and corn), particularly relative to omega-3s, may contribute to inflammatory pathways, while industrial trans fats and hydrogenated oils are clearly linked to adverse cardiometabolic outcomes18.

Fats:

• Small amounts of coconut oil, grass-fed butter, or ghee are fine for most. Choose unrefined, cold-pressed oils when possible.
• Healthy fats like extra-virgin olive oil, avocados, olives, nuts, seeds, and wild fish are anti-inflammatory and vital for hormone production.
• Limit trans and hydrogenated fats (in margarine, baked snacks) and industrial seed oils (canola, corn, sunflower, soy).

Carbohydrates: Prioritizing plants and fiber

Carbohydrates are macronutrients made up of sugars, starches, and fiber that the body converts into glucose for energy. Glucose fuels the brain and muscles, and how it’s processed and stored plays a central role in insulin signaling and metabolic health19. Carbohydrates often get a bad reputation, but they’re not the enemy—the type and amount eaten can make all the difference.

• Make most carbs plant-based: Try to fill at least half your plate with non-starchy vegetables like kale, broccoli, peppers, asparagus, leafy greens, and other cruciferous veggies. These foods are packed with fiber, vitamins, minerals, and protective phytonutrients.
• Enjoy in moderation: Whole grains such as quinoa, brown or black rice, amaranth, buckwheat, and teff, along with legumes like lentils, beans, and chickpeas, can be excellent choices. Sprouting beans or grains can even make them easier to digest20. Adding colorful vegetables, berries, and even small amounts of seaweed can expand the nutrient spectrum with unique minerals.
• Limit when needed: If you struggle with blood sugar balance or insulin resistance, it may be beneficial to go easy on starchy or high-glycemic foods like potatoes, yams, squash, and parsnips. These can raise blood sugar more quickly than non-starchy vegetables.

Micronutrients and functional compounds

Micronutrients and functional compounds may be small in size—like vitamins, minerals, and plant-derived bioactives—but their impact on health can be profound. These nutrients act as cofactors involved in regulating metabolism, protecting cells, and optimizing long-term health21.

Vitamins: Catalysts for health

Vitamins are organic compounds that drive thousands of biochemical reactions. They’re involved in everything from turning food into usable energy to supporting the immune system, making them key for both daily function and long-term health. Some are fat-soluble—such as vitamins A, D, E, and K—and can be stored in the liver and fat tissue for later use22. Others are water-soluble—such as the B vitamins and vitamin C—and aren’t stored in the body, meaning they’re used up more quickly and need to be consumed regularly 23.

Getting enough of these vitamins, whether through a nutrient-dense diet or supplementation when needed, supports critical processes like vision, bone health, antioxidant defense, and hormone balance. In certain situations—such as when biomarker results show low levels, or when your body has increased nutrient demands—thoughtful supplementation may help bridge the gap.

Foods rich in vitamins:

• Leafy greens (spinach, kale, chard): Vitamins A, C, K, and folate.
• Berries (blueberries, strawberries, blackberries): Vitamin C and polyphenols.
• Citrus fruits (oranges, grapefruit, lemons): Vitamin C.
• Sweet potatoes and carrots: Beta-carotene (vitamin A precursor).
• Eggs (pasture-raised): Vitamins A, D, E, and B12.
• Fatty fish (salmon, sardines, mackerel): Vitamins D and B12.
• Nuts and seeds (almonds, sunflower seeds): Vitamin E and some B vitamins.
• Legumes (lentils, beans): Folate and other B vitamins.

Minerals: Structural and regulatory building blocks

Minerals are inorganic elements that serve as structural components of bones and teeth, maintain fluid balance, support nerve transmission, and act as cofactors for enzymes. Some minerals, known as macro-minerals—like calcium, magnesium, potassium, and sodium—are needed in larger amounts. Others, called trace minerals, are required only in tiny amounts but are just as vital. Zinc, selenium, copper, and iodine, for example, support thyroid hormone production, antioxidant defenses, and immune system balance24,25.

One of the best ways to support healthy mineral levels is by focusing on a diet built around whole, minimally processed foods. Leafy greens, legumes, nuts, seeds, whole grains, seafood, dairy, and lean proteins can contribute a balanced mix of essential minerals the body depends on. You can also give your diet a gentle boost by including mineral-rich waters or bone broths. Testing biomarkers may be helpful to detect deficiencies and guide more targeted support when needed.

Foods rich in minerals:

• Leafy greens (collards, kale, spinach): Magnesium, calcium, and potassium.
• Nuts and seeds (pumpkin, chia, sesame, flax): Magnesium, zinc, and copper.
• Seafood (oysters, mussels, shrimp): Zinc, selenium, and iodine.
• Dairy or fortified plant alternatives: Calcium, phosphorus, and potassium.
• Legumes (beans, lentils, chickpeas): Iron, magnesium, and potassium.
• Whole grains (quinoa, buckwheat, oats): Magnesium, manganese, and iron.
• Bananas and avocados: Potassium and magnesium.
• Seaweed (nori, kelp, wakame): Iodine and trace minerals.

Fiber: Metabolic and microbiome ally

Fiber isn’t the most glamorous part of a diet, but its benefits are wide-reaching. Yet most Americans fall far short of getting enough—nearly 95% of adults don’t meet daily fiber recommendations26. The good news is, small, consistent changes can make a big difference.

Soluble vs. insoluble fiber: Different roles, shared benefits

The two main types of fiber—soluble and insoluble fiber—work differently in the body but are equally important. Soluble fiber dissolves in water to form a gel-like substance in the gut. This slows digestion, helping steady blood sugar levels and lower LDL cholesterol27, while nourishing beneficial gut bacteria28. Insoluble fiber does not dissolve in water. Instead, it adds bulk to stool to help keep digestion moving smoothly. Together, these fibers create a powerful partnership29.

Over time, high-fiber diets have been linked to reduced risk of heart disease thanks to their ability to lower blood pressure, decrease inflammation, and improve cholesterol balance30. They can also support weight management, since high-fiber foods are filling, curb appetite, and may help control calorie intake31. The average American adult consumes approximately 17 g of fiber per day32. However, research suggests that aiming for 30-50 g per day is associated with improved metabolic health, cardiovascular health, and lower all-cause mortality32,33.

Top fiber sources:

• Fruits: Apples, pears, berries, oranges, bananas
• Veggies: Broccoli, carrots, Brussels sprouts, kale, spinach
• Legumes: Beans, lentils, peas, chickpeas
• Nuts/seeds: Almonds, chia, flaxseed, walnuts
• Gluten-free grains: Amaranth, millet, buckwheat
• Root vegetables: Sweet potatoes, yams, beets (skin on)

Herbs and spices: Health multipliers

Herbs, spices, and condiments can do far more than make your meals taste good—they can provide health-promoting properties.

Powerful spices for daily defense:

• Black pepper (piperine): Can boost nutrient uptake and has anti-inflammatory and antioxidant properties34.
• Cardamom: Eases digestion, fights bacteria35.
• Cayenne (capsaicin): Boosts metabolism, may decrease pain36.
• Cinnamon (cinnamaldehyde): Improves insulin sensitivity, anti-inflammatory37.
• Cloves (eugenol): Potent antioxidant and anti-inflammatory38.
• Cocoa (flavanols, theobromine): Rich in antioxidants, supports vascular health and blood flow, may improve cognition and mood39.
• Garlic (allicin): Strengthens immunity, reduces blood pressure40.
• Ginger (gingerol): Antioxidant, anti-inflammatory41.
• Oregano (carvacrol, thymol): Antimicrobial, anti-inflammatory42.
• Saffron (crocin, safranal): Powerful antioxidant, mood support43.
• Turmeric (curcumin): Robust anti-inflammatory and boosts the body's own antioxidants44.

Fermented foods

Fermented foods are another great example of how what’s on the plate can do more than just satisfy hunger—they actively nourish the gut and promote a balanced microbiome, improving digestion. Take apple cider vinegar, for example: it’s been shown to support digestion, help regulate blood sugar, and provide antioxidant protection45. Foods such as kimchi and sauerkraut are rich in beneficial probiotics and organic acids that can make it easier for the body to absorb nutrients, get more benefit from dietary fiber, and help maintain a balanced gut microbiome46.

Phytonutrients: Powerful plant defenses

Phytonutrients—also called phytochemicals—are natural compounds found in plants that pack powerful health benefits, even though they aren’t considered “essential” nutrients. They’re abundant in colorful fruits, vegetables, nuts, legumes, whole grains, and teas. These compounds act as antioxidants and anti-inflammatory agents, helping to protect cells from damage, strengthen immune defenses, and lower the risk of chronic conditions47,48.

They can also promote healthy blood vessels, regulate cholesterol and blood sugar, and support gut health by feeding beneficial microbes and improving nutrient absorption. Eating a wide variety of colorful, plant-rich foods daily is a great way to help foster a resilient and vibrant body47,48.

• Flavonoids (apples, onions, berries, broccoli, dark chocolate, teas): Can lower inflammation and promote vascular and brain health49.
• Carotenoids (carrots, sweet potatoes, leafy greens, tomatoes): May boost eye and immune health50.
• Polyphenols (coffee, berries, grapes, olive oil, peanuts): Combat oxidative stress, improve brain function and blood sugar control51.
• Glucosinolates (broccoli, brussels sprouts, cabbage): Support detox and may lower cancer risk52.
• Phytoestrogens (flaxseed, sesame, soy, beans): Help balance hormones, bone, and heart health53.
• Saponins alkaloids (legumes, beans, spinach, chili, tea): Support cardiovascular and immune health54.

The Science of Food

From calories to code: Nutrigenomics

Nutrigenomics is the science of how diet interacts with DNA. In simpler terms, different foods can either “turn on” or “turn off” specific genes (gene expression)—affecting metabolism, inflammation, and disease risk55,56. Over time, these gene-diet interactions can meaningfully shape health trajectories, not just short-term outcomes. This may help explain why some people respond differently to the same diet and highlights the value of a personalized nutrition approach.

Food as a regulator

The foods you choose send powerful instructions that shape how your body works on the deepest level. The nutrients you eat are broken down inside the mitochondria—the cells’ power plants—which convert these nutrients into adenosine triphosphate (ATP), the energy currency that drives every body function, from muscle movement to brainwaves57. Healthy mitochondria are vital for immunity, memory, metabolism, and keeping the aging process at bay58. Whole, nutrient-dense foods can help support these powerhouses and support vitality59. From blood sugar control to inflammation, certain foods can shift measurable markers of health in ways that can either protect or harm long-term health. For example:

• Blood sugar and insulin resistance: Diets high in added sugar and refined carbohydrates can cause blood sugar spikes. Over time, this can overwhelm cells, making them less responsive to insulin—a condition called insulin resistance—which can increase the risk for type 2 diabetes60.
• Cholesterol and lipids: Processed foods high in poor-quality fats and additives can disrupt healthy lipid metabolism, raising the risk for heart disease61,62.
• Inflammation: A steady diet of sugar and processed foods can also keep inflammatory signals switched on, measured by markers like hs-CRP. This chronic inflammation can accelerate aging and may raise the risk of chronic disease63,64.

The encouraging news is that choosing mostly whole, unprocessed foods—like colorful plants, healthy fats, and clean sources of protein—can quickly impact these biomarkers62.

Understanding Nutrition Science: Separating Fact from Fiction

Nutrition advice often feels confusing because the science is complex, constantly evolving, and easily distorted65. Studies may contradict as new evidence emerges, and it’s often hard to isolate the effects of diet from other healthy behaviors like exercise or sleep66. Industry funding and attention-grabbing media headlines can further skew how findings are presented, while individual differences—such as genetics, gut microbiome, and lifestyle—mean there’s no single diet that works for everyone55. On top of that, nutrition research itself has limits: observational studies can’t prove cause and effect, clinical trials are often short and small, and diet data relies heavily on imperfect self-reporting67,68,69. Furthermore, focusing on single nutrients often oversimplifies how food actually works in the body70.

Despite the noise, the most reliable nutrition guidance is surprisingly consistent. Strong evidence supports prioritizing whole, minimally processed foods and overall dietary patterns rather than chasing fad diets or individual nutrients70. Because people respond differently to food, the best approach combines solid science with personal feedback—paying attention to how foods affect your energy, digestion, mood, and biomarkers55. In practice, sustainable nutrition is less about perfection and more about quality, awareness, and gradual adjustments that fit your lifestyle.

Nutrition in Everyday Life: Fueling Body and Mind

As we explore how food influences biology, here’s what evidence-based nutrition can mean in your daily experience—and how you may feel the impact from every meal.

Daily energy and focus

Balanced nutrition provides a steady supply of fuel to your cells and organs. Skipping breakfast or eating only a pastry with coffee in the morning may give you a temporary lift, but it can set you up for a mid-morning crash. In contrast, meals built around protein (like eggs, lentils, or beans), healthy fats (like avocado or nuts), and fiber (like veggies or berries) can help keep your blood sugar steady, may support sustained energy, and curb cravings later in the day71.

Try this: Swap a sugar-heavy breakfast for one featuring protein, fiber, and healthy fat and notice how your focus, energy, and mood shift.

Cognitive clarity and mood

Have you ever noticed how a heavy meal can make your brain feel sluggish, while a colorful salad or snack of nuts and berries leaves you feeling sharper? That’s not just your imagination. Brain-friendly nutrients like omega-3 fats, antioxidants, and B vitamins—often found in leafy greens, fish, nuts, seeds, and berries—have been linked to clearer thinking, steadier mood, and protection from age-related memory issues72.

Diets high in ultra-processed foods, sugary drinks, and unhealthy fats have also been linked to a greater risk of depression and “brain fog”73. These foods may drive inflammation in the brain and disrupt important chemical signals that support mental clarity and emotional balance74. Eating for your brain is eating for your best self—both now and in the future.

Try this:

• Add leafy greens daily: Spinach, kale, and arugula are rich in vitamins and polyphenols that have been linked to sharper memory and slower brain aging75.
• Include fatty fish: Salmon, sardines, and mackerel supply that omega-3s may help with memory, alertness, and even mood76.
• Snack on nuts and seeds: Walnuts, almonds, and flaxseeds offer vitamin E and healthy fats that may benefit mental performance77.

Performance and recovery

Your muscles don’t just run on movement—they run on nutrition. What you eat before and after activity can have a big influence on how strong you feel, how quickly you bounce back, and how well you perform over time. Protein-rich foods like salmon, chicken, or lentils can give your muscles the basic materials they need to repair and grow stronger after exertion. Minerals such as magnesium and potassium—abundant in leafy greens, beans, and seeds—can help regulate muscle contraction, prevent cramping, and may keep your energy steady. While antioxidant-rich vegetables and fruits may help counteract the stress that exercise puts on your body, speeding recovery and reducing soreness78,79.

Try this: After exercise or physical exertion, refuel with a combination of protein, vibrant vegetables, and a drizzle of olive oil. This simple combination may support repair, reduce inflammation, and speed up recovery.

Inflammation and oxidative stress

Ongoing fatigue, frequent illness, or stubborn aches are often signs of low-grade inflammation. Diet may play a huge role here. Ultra-processed foods, added sugars, and trans fats can act like fuel to the fire, ramping up inflammatory signals and increasing oxidative stress80. Small, smart swaps in your daily meals may calm inflammation and can support oxidative pathways81.

Try this: Choose sparkling water instead of soda, swap white bread for nutrient-rich options like quinoa, sweet potato, or wild rice, and boost your intake of omega-3s with salmon, walnuts, chia seeds, or sardines. Finally, aim to fill your plate with a variety of colorful vegetables—the more colors you eat, the more protective plant nutrients you are providing the body82.

Immune defense

The strength of your immune system is closely tied to food. A diet rich in colorful plants, healthy fats, and key micronutrients can help immune cells work more effectively, support recovery, and strengthen the body’s natural defenses against illness83.

Specific foods—like almonds, spinach, citrus fruits, red bell peppers, pomegranate, kiwi, garlic, ginger, and passion fruit—are especially powerful because they deliver antioxidants such as vitamins C, E, and A, along with plant compounds like flavonoids and carotenoids. These nutrients can reduce inflammation, fight harmful microbes, and may help keep your immune system resilient84. Eating a wide variety of fruits, vegetables, nuts, seeds, and spices on a regular basis has been shown to strengthen immune defenses, lower the risk of infections, and protect against chronic diseases85,86.

Try this: Aim to make half your plate vegetables at most meals, add a source of healthy fat like olive oil or nuts, and rotate your fruits to include a rainbow of colors.

Food and hormones

Food has a powerful influence on your hormones—the chemical messengers that affect everything from energy and mood to metabolism, reproductive cycles, and even how we age. Small dietary shifts can ripple into big changes in how these signals work, both day-to-day and over the long haul.

For women:

Highly processed foods, excess sugar, and unhealthy fats can worsen PMS, aggravate PCOS symptoms, and increase menopausal complaints87. Over time, these foods may also raise the risk of hormone-related cancers88. Environmental toxins from pesticides, plastics, and industrial farming can mimic estrogen in the body, disrupting normal balance89. On the other hand, fiber from flaxseed and cruciferous vegetables—like cabbage, kale, and broccoli—may help the body clear metabolized estrogens and can promote steadier hormone cycles90.

Try this: Add ground flaxseed to your breakfast and make cruciferous veggies a daily staple.

For men:

Diets high in sugar and refined carbohydrates can lower testosterone while raising estrogen and insulin, contributing to fatigue, weight gain, and sexual dysfunction91,92. Healthy fats can be key here, as fats from wild fish, eggs, avocados, and olives may support testosterone production and fertility93,94.

Try this: Swap a white bread sandwich and soda for a salmon salad topped with olives and avocado.

For everyone:

Blood sugar swings—often caused by skipping meals or relying on sugary snacks—can trigger insulin and cortisol spikes. This may leave you tired, moody, and craving more sugar95. Meals that combine protein, fiber, and anti-inflammatory fats can help stabilize these hormones, reduce cravings, and support metabolism96.

Try this: Build each meal with a foundation of protein (like beans, wild fish, or pasture-raised eggs), a source of healthy fat (like nuts or olive oil), and plenty of greens.

Meal timing

Throughout the day, spacing meals and snacks about three to four hours apart can help support digestion and maintain steady blood sugar. This spacing also allows the migrating motor complex (MMC)—a natural, wave-like pattern of gut contractions that occurs during periods without food—to do its job of moving residual food and bacteria through the digestive tract. Frequent grazing or constant snacking may interrupt this process in some individuals and contribute to symptoms like bloating or discomfort97. Try to avoid eating too close to bedtime—ideally finishing the last meal two to three hours before bed—as this can benefit both metabolism and sleep quality98,99.

Some people may find intermittent fasting or time-restricted eating (TRE) beneficial. This usually involves leaving a 12–16 hour gap between the last meal of the day and the first meal the following morning. Research suggests this approach may improve blood sugar control, support metabolic health, and even promote longevity100.

That said, intermittent fasting and TRE are not appropriate for everyone. The best approach depends on factors such as age, activity level, lifestyle, and medical context. For those who do find it helpful, simply finishing dinner earlier in the evening and eating breakfast after a consistent fasting period may offer many of the benefits, with adjustments based on individual needs and health goals.

Bringing it together

Making small, steady upgrades to your diet—like adding more cruciferous vegetables, choosing healthy fats, and keeping protein and fiber consistent—can create powerful impacts on your health. Over time, these shifts may support steadier energy, clearer thinking, faster recovery, more balanced hormones, and a stronger immune system. Think of each meal as a fresh opportunity to invest in your health—one delicious, enjoyable choice at a time.

Foods, Key Nutrients, and Functional Benefits

How to personalize nutrition

The most useful nutrition guidance doesn’t start with a diet—it starts with understanding context. How food affects the body depends on many moving pieces—including biological factors, like digestion, blood sugar regulation, inflammation, and life stage—daily routines, health goals, as well as personal values. All of these can change over time. The most effective approach focuses on what matters most right now, then making informed, flexible food choices that can adapt as needs and circumstances shift110,111.

The sections below share common situations that can influence nutrition choices. These examples are meant to serve as helpful guidance—not strict rules—and to support adjustments that feel realistic, sustainable, and aligned with long-term health.

Digestive distress or food reactions

Digestive comfort can play a big role in how well an eating plan works. Common symptoms—like bloating, gas, heartburn, irregular bowel movements, post-meal fatigue, or skin reactions—can affect daily comfort and quality of life112.

For many people, the first step is simply noticing patterns and making small, practical changes—such as adjusting portion sizes, eating more slowly, balancing meals, or cutting back on processed foods. In some cases, temporarily removing certain foods can help clarify what the body tolerates best. Short-term, structured approaches—like a low-FODMAP diet—are sometimes used to identify triggers, especially for those with irritable bowel symptoms. These approaches are not necessary for everyone and are intended as short-term tools, not permanent eating patterns113.

When digestive symptoms are persistent or disruptive, working with a healthcare professional can help ensure nutritional balance and appropriate next steps (See Gut Health 101 for more detail).

Blood sugar or metabolic issues

How the body responds to carbohydrates can influence appetite, mood, energy levels, and overall metabolic health. Some people notice energy highs and crashes, strong cravings, difficulty maintaining a healthy weight, or a family history of metabolic conditions that may warrant closer attention to blood sugar balance. Building meals around adequate protein, fiber-rich vegetables, and healthy fats can help promote steadier energy levels114.

Simple tools like symptom tracking (where you pay attention and record any symptoms experienced following a meal)—and in some cases, glucose monitoring—can offer insight into how different foods or eating patterns affect energy and satiety. The goal is not to eliminate carbohydrates entirely, but to find an approach that supports stable energy and metabolic health over time.

Autoimmune, inflammation, or allergy concerns

Inflammation can influence how the body responds to food and may be linked to ongoing symptoms like joint pain, headaches, fatigue, skin changes, or digestive discomfort. When this is the case, nutrition guidance commonly focuses on an anti-inflammatory eating pattern—emphasizing whole, minimally processed foods that support immune function and tissue repair5.

For more complex or persistent symptoms, some people may explore short-term elimination approaches to better understand which foods worsen symptoms. Highly structured protocols like the Autoimmune Protocol (AIP) are sometimes used in clinical settings for this purpose115. These approaches are intentionally restrictive and are best viewed as temporary learning tools, rather than long-term solutions. Because they can increase the risk of nutrient gaps, they’re most appropriate when done with professional guidance.

Vegan or vegetarian eating patterns

Vegan and vegetarian eating patterns can be a healthy and effective approach, but they work best with thoughtfully planning to support nutritional adequacy over time. One key area to pay attention to is protein quality. Protein is made up of amino acids, nine of which are essential and must come from the diet. A complete protein is one that provides all essential amino acids in sufficient amounts, while many plant-based protein sources are incomplete on their own. Regularly combining complementary foods—such as legumes with grains—or including complete plant proteins like soy or tempeh, can help meet essential amino acid needs116.

Plant-based eating patterns can also benefit from mindful attention to certain micronutrients that can be harder to obtain or absorb from plant foods alone. These include vitamin B12, iron, zinc, calcium, iodine, and omega-3 fatty acids. Thoughtful food choices, along with the use of fortified foods or supplements when appropriate, can help ensure nutritional needs are met and support long-term nutritional balance117.

Pregnancy, postpartum, or family planning

Pregnancy and the postpartum period involve significant shifts in nutritional needs to support hormonal changes, tissue growth, and fetal or infant development. Nutrition guidance during these stages typically emphasizes regular, balanced meals that provide sufficient protein and key nutrients for growth and neurological development—such as folate, iron, iodine, calcium, choline, vitamin D, and omega-3 fatty acids (particularly DHA). Because appetite, nausea, and food tolerance can change, flexibility is an important part of making nutrition both effective and realistic118.

After birth, the postpartum and breastfeeding periods continue to draw on nutrient stores as the body recovers and supports milk production. Overly restrictive eating during this time can interfere with healing and hormone balance. For those planning pregnancy, nutrition strategies often focus on supporting ovulation and building nutrient reserves ahead of conception, helping set the stage for a healthy pregnancy119.

Pegan principles—a practical philosophy

This approach isn’t a “diet”, but a principled nutritional philosophy that focuses on combining nutrient dense foods. It brings together the strengths of two popular ways of eating: paleo and vegan. From paleo, it takes the focus on higher-quality proteins and fewer processed foods. From vegan, it borrows an emphasis on plants—rich in fiber, vitamins, and powerful phytonutrients. Together, this approach can help support heart and metabolic health, steady blood sugar, reduce inflammation, and nourish a healthy gut microbiome. When done with flexibility, it can offer many of the same benefits we see in the Mediterranean diet—one of the most well-studied ways of eating120.

Foods to focus on: Your functional grocery list

Healthy eating starts in the grocery store. A simple rule of thumb: shop the perimeter. That’s where you’ll usually find fresh produce, meats, and eggs. Prioritize whole, nutrient-rich foods here, and be cautious in the inner aisles where processed snacks tend to live. Don’t just trust the front of the package—flip it over and look for short, recognizable ingredient lists.

You can also stretch your budget without sacrificing quality. Buy in bulk, stock up on frozen vegetables, and include affordable proteins like eggs and beans. For produce that’s more likely to carry pesticide residues—like spinach, strawberries, grapes, apples, potatoes, and peppers—choose organic or regeneratively grown when possible. Think of this list as your roadmap for healthier shopping, cooking, and eating:

Meat, poultry, and eggs

• Grass-fed and pasture-raised beef, bison, elk, lamb, pork, and venison: Higher in nutrients and healthy, anti-inflammatory fats121.
• Pasture-raised or organic poultry (chicken, duck, turkey, eggs): More nutrient-dense, less likely to contain added hormones or antibiotics122.

Fish

• Wild-caught, low-mercury fish (anchovies, herring, mackerel, oysters, salmon, sardines): Best for omega-3s and minimal toxins123.

Dairy

• Grass-fed butter, homemade yogurt, ghee: Nutritional fats and vitamins124.
• Grass-fed goat or sheep milk/cheese: Easier to digest, more nutrient-rich125.
• Fermented dairy: Yogurt and kefir, especially from goat/sheep or A2 cows126,127.

Vegetables

• A rainbow of organic veggies: Artichokes, arugula, asparagus, bok choy, broccoli, Brussels sprouts, cauliflower, celery, collards, fennel, kale, mustard greens, onions, peppers, radicchio, spinach, squash, tomatoes, sweet potatoes, zucchini108.
• Organic: Provides fewer pesticides and richer phytonutrient profiles128.

Fruits

• Organic avocados, berries, coconuts, kiwis, lemons, limes, olives, pomegranates: Rich in fiber, vitamins, antioxidants129.

Fats and oils

• For cooking: Grass-fed butter/ghee, humanely raised tallow, lard, duck/chicken fat, avocado oil, virgin coconut oil130.
• For salads: Almond, flax, hemp, macadamia, extra-virgin olive oil, sesame, tahini, walnut oil.

Beans and legumes

• Green beans, peas, lentils, gluten-free soy, tempeh, miso, natto, soy: Great fiber, prebiotic, and plant protein sources131.

Grains

• Organic, non-GMO, gluten-free (amaranth, black rice, buckwheat, millet, quinoa, brown rice): Nourish the microbiome, can help stabilize blood sugar, and may play a role in calming inflammation131.

Nuts and seeds

• Almonds, Brazil nuts, cashews, chia, flaxseed, hazelnuts, hemp, macadamia, pecans, pistachios, pumpkin, sesame, walnuts: Provide healthy fats, minerals, protein131.

Natural sweeteners

• In small amounts: Pureed fruit, monk fruit132, organic stevia133.

Beverages

• Water (plain or with sliced fruit/cucumber), herbal teas, high-quality coffee: With no added sugars or artificial chemicals134.
• Daily water intake recommendations: Can vary, but generally, men should aim for around 15.5 cups (3.7 liters) and women for 11.5 cups (2.7 liters). These are averages, and individual needs can fluctuate based on factors like activity level, climate, and overall health135. A simple first step is to start your morning with a glass of water to rehydrate after sleep. Adding a squeeze of lemon or a few mint leaves not only boosts flavor but may also provide subtle health benefits.
• Protein shakes: Packed with fiber/veggies/good fats.

Herbs, spices, and phytonutrients

• Herbs and spices: Such as turmeric, ginger, garlic, black pepper, cinnamon, cardamom, cloves, oregano, and saffron not only boost flavor but can deliver science-backed antioxidant, anti-inflammatory, and sometimes antimicrobial effects136.

What is regenerative agriculture—and why does it matter?

Regenerative agriculture takes farming a step further than “organic.” It’s a farming approach designed to heal and strengthen entire ecosystems—especially the soil. Regenerative practices aim to actively restore and enrich the natural resources that make our food possible. It’s a practice that is not only about protecting the land—it’s about bringing it back to life137.

Core principles and practices include:

• No-till or low-till farming (can protect soil microbes and structure)
• Planting cover crops between harvests
• Rotating crops to boost soil nutrients and manage pests naturally
• Holistic grazing—moving animals to fertilize and aerate soil
• Agroforestry—using trees and diverse plants for shade, water retention, and carbon capture

Benefits—for People and Planet:

• Better nutrition: Healthier soil can grow more nutrient-rich food, improving what ends up on your plate.
• Fewer chemicals: Regenerative farmers avoid pesticides and synthetic fertilizers, resulting in cleaner, safer food.
• Climate health: These practices can trap atmospheric carbon, restore water cycles, and may make farms more resilient to climate change.
• Supporting communities: Regenerative methods help rural economies and can preserve farming wisdom for future generations.

Foods to avoid (and why)

Ultra-processed foods

Processed foods are foods altered mainly for preservation or convenience—such as freezing, canning, fermenting, or cooking. Many can still be part of a healthy diet, including plain yogurt and frozen or canned vegetables without additives. Ultra-processed foods (UPFs) go much further. They are typically stripped of fiber and key nutrients and engineered for taste, texture, and shelf life. Common examples include packaged lunch kits, squeezable yogurt pouches, chips, crackers, candy bars, many breakfast cereals, and soft drinks. High intake of UPFs is linked to metabolic dysfunction, impaired gut health, increased cravings, and higher risk of chronic disease138. Today, UPFs make up more than 60% of the Standard American Diet and account for about 90% of all added sugar intake138,139.

What’s hiding in ultra-processed foods?

• Additives and preservatives (carrageenan, gums, emulsifiers): Used to thicken, preserve, or modify texture, these can damage the gut lining and have been associated with autoimmune reactions and gut disorders140.
• Artificial sweeteners, colors, and flavors: Can disrupt gut and metabolic health, and may even impact mental health141.
• Refined sugars: Accounting for the majority of added sugar intake, which can spike blood sugar, drive cravings, and may promote inflammation and mood swings142.
• Refined seed oils and trans fats: Diets high in refined omega-6–rich seed oils relative to omega-3s may contribute to inflammatory pathways, while industrial trans fats are strongly linked to adverse metabolic effects143.

Quick tip: Try building meals and snacks around single-ingredient staples—for example, swap flavored instant oatmeal for rolled oats topped with fruit, or replace packaged salad dressings with olive oil, lemon juice, and herbs.

Key foods and ingredients to watch for

Ultra-processed foods are major offenders, but they’re not the only concern. There are other ingredients and food types that can have negative effects on energy, metabolism, gut health, and hormone balance. Here’s a practical guide to what’s worth limiting—or avoiding altogether—and why it matters.

• Processed and conventional meats (bacon, deli meats, hot dogs, factory-farmed eggs/poultry): Consider avoiding as they are often loaded with additives, preservatives, antibiotics, hormones, and unhealthy fats, all of which are linked to inflammation, increased risk of chronic disease, and disruptions to healthy metabolism144,145.
• High-mercury fish (tuna, swordfish, Chilean sea bass): Best limited or avoided, as the risk of mercury and other toxin exposure in these species often outweighs the nutritional benefits, potentially harming the nervous system and overall health146.
• Conventional dairy (and A1 casein products): More likely to contain hormones, antibiotics, and can cause inflammation and digestive distress; opting for goat, sheep, or A2 cow’s milk products may reduce these risks and be easier to tolerate for many people147.
• Certain non-organic veggies or fruits: Some of the fruits and vegetables found to have the most pesticide residues when grown non-organically include strawberry, spinach, kale, nectarine, apple, grape, peach, cherry, pear, tomato, celery, and potatoes148. These foods tend to absorb or hold onto more pesticides because of their thin or porous skins, which offer less protection than thicker-skinned produce like avocados or bananas. Choosing organic versions of these foods can help reduce exposure.
• Modern wheat/gluten: Current wheat is high in problematic starches and gluten proteins that can spike blood sugar and may promote leaky gut and inflammation even in non-celiacs149,150.
• Vegetable and industrial oils: Canola, soybean, corn, sunflower, safflower, trans fats, and margarine should be minimized because they have been linked to inflammation, oxidative stress, and negative metabolic impacts when used in excess or frequently consumed143.
• Artificial sweeteners and high-glycemic sugars: Agave, aspartame, corn syrup, sucralose, sugary sodas, and juice might be best if avoided or minimized as they can disrupt metabolism, may harm gut health, and either spike blood sugar or increase cravings for more sweets151.
• Alcohol, enhanced “sports” drinks, most flavored/energy drinks: Not recommended as they often contain hidden sugars, artificial ingredients, and other additives that can negatively impact liver health, blood sugar, and overall metabolic health152,153.
• Sugar-sweetened drinks: Contain concentrated sugars that contribute to blood sugar spikes and metabolic disruption154.
• Diet sodas: Although sometimes marketed as healthier options, these do not significantly benefit body weight155, may harm gut microbes, and can negatively impact metabolic health156.
• Fruit juices: Even “green juices” can pack as much sugar as a soda. When fruit is juiced, the fiber—which can slow sugar absorption, support digestion, and help you stay full—is stripped away. The result can be a spike in blood sugar. Check labels carefully and aim for drinks with no more than five grams of sugar when possible.

Building balanced meals

Think of a balanced plate as a simple formula you can use at every meal. Start with the “half-plate rule”: fill half your plate with vegetables—raw, roasted, steamed, or tucked into a salad or stir-fry. The remaining space can be divided between a palm-sized portion of high-quality protein, such as wild fish, regeneratively raised poultry or eggs, beans, or organic tofu, and a source of healthy fats, such as nuts, seeds, avocado, olive oil, or a tahini-based dressing. This combination delivers essential nutrients, supports satiety, and can provide sustained energy.

How you combine foods matters, too. Pairing carbs with protein, fiber, or healthy fats can slow down sugar absorption, prolong fullness, and may help prevent blood sugar spikes157. Even the order you eat can make a difference—starting with non-starchy veggies, then protein and fats, and finishing with starches or fruit has been shown to reduce cravings and smooth out blood sugar swings later in the day158. Finally, aim for variety. The more colorful your plate, the broader the range of antioxidants and plant compounds you’re providing the body108.

Sample meals to try:

• Breakfast: Sautéed spinach and cherry tomatoes topped with a pasture-raised egg or two, half an avocado, and a sprinkle of hemp seeds or walnuts. Add a small side of berries.
• Lunch: Arugula salad loaded with roasted vegetables, grilled chicken, walnuts, and a drizzle of olive oil vinaigrette.
• Dinner: Fish taco bowl with grilled fish, cabbage slaw, salsa, black beans, avocado, on a base of quinoa.

Set yourself up for success by doing a little prep on the weekend. Roast a tray of veggies, cook a pot of grains, or prepare proteins in advance. Having these basics ready to go makes it much easier to throw together quick, nourishing meals and lowers the stress of figuring out what’s for dinner.

Eating out and on-the-go: Making healthy choices

Maintaining a healthy eating pattern can be challenging when you're dining out or constantly on the move. However, with a little planning and awareness, you can still make nutritious choices that support your health.

Customizing your plate

Eating out doesn’t mean you have to give up on eating well. Most restaurants are willing to make adjustments if you ask. Here are a few easy ways to customize your plate for a healthier option:

• Ask for extra veggies: Many dishes can benefit from an extra serving of vegetables. Requesting additional non-starchy vegetables like broccoli, spinach, or green beans can boost your fiber and nutrient intake without piling on calories.
• Swap the fries: French fries are a common side dish, but they are often deep-fried and high in unhealthy fats. Opt for a side salad with olive oil and vinegar or lemon as a dressing (or ask for dressing on the side) to increase your vegetable intake and reduce unhealthy fats.
• Choose grilled over fried: Fried foods are typically higher in calories, unhealthy fats, and sodium. When possible, select grilled, baked, broiled, or roasted proteins and vegetables. This simple switch can significantly reduce the unhealthy fat content of your meal.
• Be mindful of sauces and dressings: Sauces and dressings can be hidden sources of sugar, unhealthy fats, and sodium. Ask for sauces and dressings on the side so you can control the amount you use.
• Manage portions: Restaurant portions are often much larger than a single serving. Consider sharing an entrée, asking for a half portion, or box up half for later.

Packing smart snacks

Having healthy snacks on hand is one of the best ways to avoid grabbing whatever’s quick but not so healthy when hunger hits. A little planning can go a long way. Here are some easy, nourishing options:

• Nuts and seeds: A small handful of unsalted nuts (almonds, walnuts, cashews) or seeds (chia, flax, pumpkin) can provide healthy fats, protein, and fiber, helping you feel full and energized. Portion them out to avoid overeating.
• Vegetables: Vegetables like carrot sticks, cucumber slices, bell pepper strips, or cherry tomatoes are convenient, refreshing, and packed with vitamins and fiber. Pair them with a small container of hummus or a healthy dip for added flavor and additional nutrients.
• Fresh fruit: Whole fruits like apples, bananas, oranges, or berries are excellent sources of vitamins, minerals, and fiber. They are naturally sweet and easy to carry.
• Hard-boiled eggs: Hard-boiled eggs are a portable and excellent source of protein, which can help keep you satiated between meals.
• Cultured Greek yogurt (plain): If you have access to refrigeration, plain cultured Greek yogurt is a good source of protein and probiotics. You can add a few berries or a sprinkle of nuts or seeds for extra flavor and nutrients.
• Whole-grain crackers with nut butter: Choose whole-grain gluten-free (when sensitive) crackers for added fiber and pair them with a small serving of natural nut butter (almond, peanut) for healthy fats and protein.

Everyday swaps

Testing for Nutrition

Sometimes the best way to understand what your body truly needs is through advanced testing. These assessments may give a clearer picture of your unique nutritional status and help identify areas where support is needed.

Function membership: Key nutrition-related tests

With membership testing, you have access to key nutrition and metabolic tests that can serve as a foundational screen. Repeating these annually—or twice a year—can help track progress, fine-tune your dietary and lifestyle habits, and troubleshoot symptoms.

• Activity trackers/smartwatches: Monitor movement, sleep, heart rate, stress, and food/hydration logs—can be key for integrating lifestyle factors with nutritional strategies.

Key Takeaways and Action Steps

Healthy nutrition isn’t about chasing fads or obsessing over what not to eat—it’s about making consistent choices that help your body function at its best. Every bite you take sends a message to the body. That message can either support repair and resilience, or slowly work against it. The most powerful results often come from small, daily choices that add up over time.

Key takeaways

• Food is information: It’s not just fuel—it actively influences your energy, immunity, hormones, and brain health.
• Build diversity: A varied diet built on minimally processed, nutrient-dense foods can support healing, reduce inflammation, and may promote long-term vitality.
• Personalization matters: Your genetics, gut health, and lifestyle all influence how your body responds to food.
• Use feedback: Lab testing and self-tracking can provide valuable clues to help fine-tune your diet for optimal function.
• Think beyond the plate: Farming practices and environmental factors can affect both the nutrient quality of food and the toxin load it carries.
• Crowd out the junk: Cutting back on ultra-processed foods can reduce inflammation triggers and make room for more nourishing, healing options.

Action steps

• Build meals wisely: Center most meals around colorful vegetables, quality protein, and healthy fats. Over the week, aim for a range of colors and textures to support a diverse intake of nutrients.
• Pair the carbs: Combine carbohydrates with protein or fat to steady energy and support balanced blood sugar.
• Choose higher-quality foods when you can: Explore regenerative or organic options, especially for items most likely to carry pesticides or toxins.
• Flavor with function: Use herbs, spices, and fermented foods regularly to support your gut microbiome and provide antioxidant benefits.
• Keep staples on hand: Stock quick, nourishing basics like frozen vegetables, canned wild fish, nuts, and lentils so balanced meals are always within reach.
• Listen to your body: Track how different foods affect your energy, digestion, mood, and sleep. Adjust based on patterns and, when needed, lab results.
• Plan for busy days: Prep veggies, cook grains, or pack portable snacks ahead of time to avoid relying on processed foods.
• Personalize restaurant meals: Add extra veggies, swap out refined starches, and swap industrial oils for healthier options when possible.
• Stay hydrated and time your meals: Hydrate consistently with water or unsweetened beverages, and try spacing meals 3–4 hours apart for digestion and stable blood sugar.
• Use testing as feedback: Repeat labs at regular intervals to track nutrient levels, metabolic health, and inflammation—then fine-tune your nutrition accordingly.

By consistently choosing nourishing foods and using tools like Function testing for guidance, you can better understand how nutrition shapes your energy, resilience, and long-term vitality—and adjust in ways that work best for you.
